Phonics breakdown
Phonics Rule: TH Digraph (Unvoiced)
Sound“th”·/θ/
TH can make a soft sound “th”, like in 'think' and 'bath'. Just air, no buzz!
The unvoiced TH “th” is the quiet, breathy version. Your throat doesn't vibrate. Stick your tongue between your teeth and blow air.
Tip
Unvoiced TH is quiet — think with three teeth!
Examples
Phonics Rule: R-Controlled IR
Sound“er”·/ɜːr/
When R comes after I, it makes the “er” sound, like in 'bird' and 'first'.
IR makes the same “er” sound as ER and UR. There's no difference in pronunciation — only in spelling.
Tip
The bird in a shirt says “er”!
Examples
Phonics Rule: Letter T
Sound“t”·/t/
The letter T makes the /t/ sound, like in 'top', 'tap', and 'ten'. The tongue tip taps behind the upper teeth.
T is a voiceless alveolar stop. The tongue tip touches the ridge behind the upper teeth and releases with a puff of air. Double T (tt) makes the same /t/ sound.
Tip
T taps — touch your tongue to make /t/!
Examples
Phonics Rule: EE Vowel Team
Sound“ee”·/iː/
When two E's are together, they say long E, like in 'tree' and 'see'.
The vowel team 'ee' almost always makes the long E sound “ee”. This is one of the most reliable vowel teams in English.
Tip
Two E's together always agree — they say “ee”!
Examples
Phonics Rule: Letter N
Sound“n”·/n/
The letter N makes the /n/ sound, like in 'net', 'nap', and 'nut'. The tongue tip touches behind the upper teeth.
N is a voiced alveolar nasal — the tongue tip touches the ridge behind the upper teeth while voice hums through the nose. It is one of the most common consonants in English.
Tip
N hums through the nose — say /n/ and feel the buzz!
